The researchers found that several apps were used to create false interactions with ads on hidden screens, which trick advertisers into paying for a non-existent audience, including 75 apps on Android and 10 apps on iOS.
The applications discovered by researchers are all imitators of some well-known and popular games, and since then they have been removed from the App Store, namely:
• Fire-Wall
• Loot the Castle
• Ninja Critical Hit
• Racing Legend 3D
• Rope Runner
• Run Bridge
• Shinning Gun
• Tony Runs
• Wood Sculptor
While researchers have not revealed any security risks behind these apps, the way they work can affect phone performance and battery life. Additionally, the researchers warned that developers may update apps to change the way they work, so removing apps is the best option for users.
